Candy Crush Saga Level 1628 Tips and video

First you need to open up the board a bit by clearing some of the blockers and chocolate, there's no need to clear the whole board to start with though, the task is to score points, not clear the board, this will happen as you play.

Once you have a bit of space to work start collecting the keys, but keep looking for chances to make special candies and combos as these will give you the points you need. Don't worry if some of the keys are eaten by chocolate, they still count and will still unlock the UFO.

Switching candies aimlessly won't give you many points so you need to play carefully and try to make combos as much as possible.

The keys will unlock the UFO from the top of the board and switching that will clear any remaining chocolate or blockers. There are some mystery candies dropping from the dispensers at the top but as usual you need a bit of luck with these to get good stuff and not more chocolate or blockers, but it is worth switching them to see what you get.

Colourbombs always give the most points and you can switch them with anything else that is nearby.

If the
level you play is different from the one here it is because the developers have
changed it since I played and I have no control over this. Please let me know
in the comments and I will try to change it.
